Esports has gained global popularity in recent years and several companies have started offering live streaming videos of esports games and events. This creates opportunities to develop large scale video understanding systems for new product features and services. We present a technique for detecting highlights from live streaming videos of esports game matches. Most video games use pronounced ...

This dataset release accompanies Pinter et al. (2016) which describes the motivation and grammatical theory. Please cite that paper when referencing the dataset. The dataset may be accessed via the Yahoo Webscope homepage1 under Linguistic Data as dataset L-28. The description in Section 2 is included within the dataset as a Readme. The dataset is sure to have annotation errors which are not co...

Effectively managing multiple data centers and their traffic dynamics pose many challenges to their operators, as little is known about the characteristics of inter-data center (D2D) traffic. In this paper we present a first study of D2D traffic characteristics using the anonymized NetFlow datasets collected at the border routers of five major Yahoo! data centers. Our contributions are mainly t...

With an exploding global market and the recent introduction of online cash prize tournaments, fantasy sports contests are quickly becoming a central part of the social gaming and sports industries. For sports fans and online media companies, fantasy sports contests are an opportunity for large financial gains. However, they present a host of technical challenges that arise from the complexities...

Learning to rank for information retrieval has gained a lot of interest in the recent years but there is a lack for large real-world datasets to benchmark algorithms. That led us to publicly release two datasets used internally at Yahoo! for learning the web search ranking function. To promote these datasets and foster the development of state-of-the-art learning to rank algorithms, we organize...

We construct a budget-balanced wagering mechanism that flexibly extracts information about event probabilities, as well as the mean, median and other statistics from a group of individuals. We show how our mechanism, called Brier betting mechanism, arises naturally from a modified parimutuel betting market. We prove that it is essentially the unique wagering mechanism that is anonymous, proport...

The lp regression problem takes as input a matrix A ∈ R, a vector b ∈ R, and a number p ∈ [1,∞), and it returns as output a numberZ and a vector xOPT ∈ R such thatZ = minx∈Rd ‖Ax− b‖p = ‖AxOPT − b‖p. In this paper, we construct coresets and obtain an efficient two-stage sampling-based approximation algorithm for the very overconstrained (n ≫ d) version of this classical problem, for all p ∈ [1,...
